Average Bench: 111% (9th of 1132)

Based on 5,637 user benchmarks.  Device: BFEBFBFF000906EA Model: Intel(R) Core(TM) i7-8086K CPU @ 4.00GHz

Intel are celebrating the 40th anniversary of their x86 architecture and 8086 processor with the launch of their high-end i7-8086K. Just 50,000 units of this hex core, twelve threaded Coffee Lake processor have been made available globally. Exactly like the i7-8700K, the 8086K features 12MB of smart (L3) cache, 2 channels of DDR4 RAM and has a TDP of 95W. Essentially, the 8086K is Intel’s current Coffee Lake flagship, the i7-8700K, with a single-core turbo frequency factory overclocked by 300 MHz. Thermals permitting, out of the box, the i7-8086K achieves a single core boost speed of 5.0 GHz – which is a new record for Intel. That said, you would be unlucky if you were unable to achieve a 5.0 GHz single core OC with an 8700K. For everything other than single core, the turbo clock speeds on the 8086K exactly match the 8700K which puts the 8086K firmly into gimmick territory. Directly comparing the 8086K and 8700K shows that for a $100 (24%) price premium you get around a 5% performance improvement which drops to around 2% when both chips are overclocked. If the price gap between the 8086K and the 8700K were to fall to less than 20 USD it may be worth considering the 8086K. [Jun '18 CPUPro]

it's just a binned and overpriced 8700k

It is allready overclocked so you don't need a z370 motherboard, so the €70 more is not an issue.

...just a RE-BRAND for 100$ more.

The 5Ghz is only applied for 2 cores. The rest are identical to 8700k. This is just a binned 8700k with a fancy name. I love it, though.

Another "cheap" trick from Intel.

8700k with new name and less changes of poor overclocking, limited numbers add bit of exclusivity. Bought not for performance, but because it is a gimmick.

Pointless CPU for those who don't know how to overclock 8700k

Only an idiot would spend an extra $100 just for that 5% performance than an i7-8700k - said no one ever.

Got it for 50 more than a 8700k goes for, it's pretty much the same thing but you know it's gonna reach 5ghz without problems at 1.3v. (overclock, not turbo boost which works only on one core) Worth the 50 bucks if you are planning to use it for the decade to come.

When it was on sale it was only a tiny bit more than the 8700K, and comes stock with higher default single core speed. Generally overclocks higher without much work too. You have to give it some props for nostalgia too. I mean 40th Anniversary of the 8086. 5+ GHz official speed. People are saying $60-$100 more than 8700K... but when I bought, it was anywhere from $20-$40 more. Which to me is worth it, to them, maybe not. To each their own, but some will pay much higher to have a guaranteed 5GHz clock speed. I can run 5.2 on all cores 24/7 so I'm happy paying extra.
